Audio Trimmer

Trimming unwanted portions from audio recordings is essential work for podcasters, musicians, and anyone editing sound. Instead of struggling with complex audio software, this tool lets you visually trim audio clips to exact timestamps directly in your ブラウザ.

Visual waveform editing

After アップロードing your audio file, you see a full waveform display showing the complete recording. This visual representation helps you identify where to cut—you can see music beats, speech pauses, silence, and noise clearly in the waveform. Type precise start and end times in MM:SS フォーマット (minutes and seconds), and the tool highlights exactly what you're keeping.

Preview before export

Always preview the trimmed region before ダウンロードing to ensure you're cutting at the perfect spots. Hearing the exact audio you'll export prevents the frustration of trimming and finding the cut point was slightly wrong. The preview button plays just the selected segment so you verify the boundary points sound right.

Precise time control

Unlike dragging sliders that require approximation, type exact timestamps. Cut starting at 1:23.5 to skip an intro, end at 4:45.2 to remove an outro—timing is precise to tenths of a second. This accuracy is essential for music where beat-perfect cuts matter, or when removing specific spoken words from interview recordings.

Common workflows

Podcasters trim dead air and long pauses from interviews, musicians isolate specific song sections, audiobook narrators remove false starts and coughs, DJs extract specific beats or drops, and content creators remove silence and filler words to tighten their audio. Voice actors trim takes to perfect lines, and researchers isolate specific moments from recorded lectures.

Lossless WAV export

The trimmed audio exports as 16-bit PCM WAV フォーマット—completely lossless, compatible with every audio software, and ready for further editing or immediate use. Unlike MP3, WAV preserves perfect audio quality, making it ideal for professional work.

ブラウザ-based editing

All trimming happens locally using the Web Audio API. Your audio file stays on your computer with no server アップロードs—complete privacy and instant processing.
